A new and important study on sea levels finds: "the amount of erosion on Diego Garcia over ther last 50 years is almost exactly balanced by the amount of accretion, suggesting the island to be in a state of equilibrium." Commenting on the significance of this finding, authors Purkis et al say their study "constitutes one of the few that have documented island shoreline dynamics at timescales relevant to inform projections of future change." And the information it delivers is a damning indictment of alarmist projections of low-lying demise in response to CO2-induced global warming
